i.Qualitative and quantitative estimation of phytoplankton and zooplankton
in three seasons

ii.Determination of physico-chemical parameters and their correlation with
phytoplankton and zooplankton abundance

iii.The relationship between phytoplankton, zooplankton and fish in the food
chain of Chilka lake.

Findings:

i.Copepods are abundant and their distribution is uniform in pre-monsoon
but during monsoon they are more in central sector and during post-monsoon they
are more in central sector and in outer channels.

ii.Seasonaland spatial
variations were noticed with respect to species of phytoplankton, seaweed and
other vegetation.

iii.A total of 10-15 phytoplanktons were commonly found.

iv.Increase of salinity from 3 to 12 ppt during the year 2003 isthe key factor in distribution of zooplankton

v.The level of chlorophyll-a was found to be high in monsoon and
post-monsoon.
